Keyword Density Checker

About Keyword Density Checker

Keyword density shows how often a word or phrase appears compared with the total number of words. This tool lists your most-used words and two-word phrases with counts and percentages, ignoring common filler words. It helps writers see which topics dominate a page and spot overuse. Modern search engines look at meaning and quality, so use density as a diagnostic, not a target.

Example

Input: a 500-word blog post. Output: the top ten single words, such as garden, plants and soil, with counts, and a list of repeated two-word phrases such as raised beds.

Tips for better results

• If one word appears unnaturally often, rewrite with synonyms.
• Check that your main topic words appear in the title, headings and introduction.
• Do not aim for a fixed percentage. Write naturally.

When to use Keyword Density Checker

Use this tool after you finish a draft and before you publish, when you want an objective view of which words your text leans on. Writers, editors and SEO beginners benefit most, especially when a page feels repetitive or when you suspect the real topic is not what you meant. It also helps when comparing two versions of a paragraph. The text is analyzed in your browser and nothing is uploaded.

Real-world uses

• A blogger pastes a finished article and sees one product name appearing far more than anything else, so she rewrites a few sentences with natural variations.
• An editor compares two versions of a landing page to see which one keeps focus on the service instead of filler phrases.
• A student checks a long essay to confirm that the central concept appears often enough to show the argument stays on topic.
• A store owner reviews a product description and finds a two-word phrase repeated in every paragraph, signaling copy that needs trimming.

Common mistakes to avoid

• Treating the percentage as a target to hit encourages stuffed, awkward sentences, when the number is only a rough signal about repetition.
• Pasting a page together with menus, footers and comments adds noise, so analyze only the body text you actually wrote.
• Ignoring two-word phrases can hide overuse, because a repeated phrase may stand out even when each single word looks normal.

Frequently asked questions

Should I check density on every page?

It is most useful on long pages or drafts that feel repetitive. For short pages the numbers swing widely, so rely on a careful read-through and clear writing instead.

Why do my results change when I edit one sentence?

Density is a share of total words, so adding or removing text moves every percentage. Small edits matter more in short texts, which is why tiny samples give unstable results.

Is Keyword Density Checker free to use?

Yes. Keyword Density Checker is completely free and you do not need to create an account.

Is my data uploaded anywhere?

No. This tool runs in your browser, so what you type or choose stays on your device.

How accurate are the results?

Calculations use standard formulas, but always double-check important figures, especially for money, health or legal decisions.
